The subject is continued on folio 108 recto opposite (D03121; Turner Bequest LVI 106). Perhaps, if the inscription on that page is to be relied on, this is a scene at Auchlyne, in Glen Dochart between Crianlarich and Killin; the high mountains prominent here would tend to confirm such an idea.
Alternatively, the sketch may be wrongly identified: its context in this sketchbook suggests that it may show part of the Strath of Appin above Garth Castle. Finberg guessed that it is a mistake for Achloa,1 a tiny settlement on the south of the River Lyon east of Fortingall.
